Support assemblies

Abstract

An upwardly extending structure is secured to a based support system comprising a series of individual blocks 25 interlocked with a linking beam 26. Each incorporates a groove in its top face which receives the linking beam 26. U-shaped bolts 29 A are located in grooves formed in the two sides of the block 25 and running around the base. The ends of the bolts will be fixed to securing plates 29 B. Each block has a pair of protrusions and a pair of recesses in both side walls so that the blocks can be interlocked with one another. This reduces the need for all of the blocks to be positively attached to the linking beam 26. Thus, pairs of blocks can be unsecured to the linking beam between two blocks which are positively attached to the beam 26. Attachment plates 32 can be secured to the sides of the linking beam 26.

1 . A support base for an upwardly extending structure and comprising a series of individual blocks and a linking structure extending along the length of the line of blocks, the blocks and linking structure being releasably interlocked with one another to form the foot of the base assembly, with the linking structure also providing a mounting area for said structure.  
     
     
         2 . An assembly according to  claim 1 , wherein the blocks have substantial width, relative to their depth in the longitudinal direction of the linking structure.  
     
     
         3 . An assembly according to  claim 1 , wherein the blocks carry at their side faces interengaging protrusions and recesses so that they can be interlocked.  
     
     
         4 . An assembly according to  claim 3 , wherein a securing device interlocking the linking structure to a block is provided for only some of the blocks, with the blocks inbetween those held by securing devices being held together by said interengaging protrusions and recesses.  
     
     
         5 . An assembly according to  claim 1 , wherein each block incorporates a slot running around the sides and base of the block for receipt of a securing device in the form of a U-bolt to be secured to said linking structure or to a plate mounted above said linking structure.  
     
     
         6 . An assembly according to  claim 1 , wherein each block has a groove formed into its top face to house the extending linking structure.  
     
     
         7 . An assembly according to  claim 1 , wherein the linking structure comprises a continuous beam with upper and lower flanges in cross section, and the blocks define slots for fitting over said lower flange section of the beam to lock the blocks to the beam.  
     
     
         8 . An assembly according to  claim 7 , wherein the beam has a horizontal lower flange on which the blocks are to be located.  
     
     
         9 . An assembly according to  claim 7 , wherein the beam has a horizontal upper flange providing the mounting area for the structure to be supported.  
     
     
         10 . An assembly according to  claim 1 , wherein upright supports are secured to said linking structure.  
     
     
         11 . An assembly according to  claim 10 , wherein said supports carry hand rails.  
     
     
         12 . A mounting for an antenna, the mounting comprising an upright mounting pole, two base support members in the form of beams extending generally at right angles to one another and connected to said mounting pole and to triangulated support braces mounted between the base support members and said mounting pole.  
     
     
         13 . A mounting according to  claim 12 , wherein mounting rungs are provided on the mounting pole, together with an operating platform carried by horizontal support braces of the triangulated structure.  
     
     
         14 . A mounting according to  claim 12 , wherein parts of the triangulated structure are connected to one another by gusset plates and held by bolts.  
     
     
         15 . A mounting according to  claim 12 , and forming part of a support base assembly comprising a series of individual blocks and a linking structure extending along the length of the line of blocks, the blocks and linking structure being releasably interlocked with one another to form the foot of the base assembly, with the linking structure also providing a mounting area for said structure, wherein the base support members are provided by said linking structure.
